I want to put a simple but reliable quotation tool into my sales team’s pockets, available on both iOS and Android from a single code-base. The goal is to let a Sales Representative stand in front of a customer, take measurements, and walk away with a signed-off price in minutes, while I (Admin) keep full control of pricing behind the scenes. Core flow • Rep enters width × height; the app converts to square metres automatically. • They choose the window or door profile, select the glass type, decide on a mosquito-net option, and optionally add installation, delivery, or removal of old windows. • A live total updates with every choice and can be saved as a PDF or shared instantly. Admin privileges I need a back-office screen—cloud or local—where I can update prices, manage discounts and taxes, and view every quotation generated in the field. Key deliverables – Universal mobile app (iOS & Android) with two roles: Admin and Sales Representative – Price calculation engine based on profile, glass, mosquito net, installation, delivery, removal, and square-metre input – PDF/Share export of the finished quote – Source code and build documentation, clear enough that future updates are straightforward Once I can install, create a test quote end-to-end, and adjust a price table from the Admin side, I’ll consider the project complete.
